Technical Field
[0001] This application relates to the field of samplers, and more particularly to a multi-channel grain sampler. Background Technology
[0002] Currently, the portable grain samplers used in China are mainly bell-shaped and horizontal-shaped grain samplers. Their main feature is the ability to divide the sample into two relatively even portions.
[0003] Both the bell-shaped and horizontal-shaped sample dividers can only divide the sample into two equal parts. If three to four parts are needed, further reduction is required. The reduction process requires certain skills from the operator, who needs to have a certain foundation in sample division to divide the sample well. In addition, the previous sample division devices are not convenient for dividing grain samples into multiple equal parts, so they need to be improved. Utility Model Content
[0004] To address the problem of the inconvenience in dividing grain samples into equal portions, this application provides a multi-channel grain sample divider.
[0005] The multi-channel grain sampler provided in this application adopts the following technical solution:
[0006] A multi-channel grain sampler includes a support and a working cylinder. The working cylinder is vertically mounted on the support and extends vertically. A horizontal grid box is provided at the top of the working cylinder for dividing the grain into two equal portions. A conical channel for receiving the grain in the horizontal grid box is provided below the horizontal grid box. The conical channel is fixed to the inner wall of the working cylinder. The inner diameter of the conical channel gradually decreases from top to bottom. Several partition plates are provided below the conical channel. The partition plates are arranged radially with the central axis of the conical channel as the center. The distance between adjacent partition plates is equal. The ends of the partition plates near the central axis of the conical channel are fixed to each other, and the other ends are fixed to the inner wall of the working cylinder.
[0007] By adopting the above technical solution, during use, the grain is poured into the horizontal grid box, and the grain is divided into two equal portions that are discharged from the bottom of the horizontal grid box, achieving initial separation of the grain. Then, the two equal portions of grain fall simultaneously into the conical channel, where the grain is mixed again. At this point, the grain in the conical channel is more uniform, allowing the grain to be discharged evenly from the bottom of the conical channel. When the grain falls to the dividing plate, it is evenly discharged from the working cylinder between adjacent dividing plates, thus obtaining multiple uniform portions of grain at once, making the operation convenient.
[0008] Optionally, a guide channel is connected between adjacent partition plates, and a plurality of guide channels are provided below the partition plates, wherein the inner diameter of the guide channels gradually decreases from top to bottom.
[0009] By adopting the above technical solution, when the grain passes through the separator, it passes between the adjacent separators and enters the guide channel. The guide channel plays a guiding and separating role, so that multiple uniform portions of grain will not mix during the fall, thus making it easier to collect each portion of grain.
[0010] Optionally, a conical block is provided between the partition plate and the conical channel. The conical block is fixed on the partition plate, and the conical block is coaxial with the central axis of the conical channel. The top of the conical block is a pointed tip.
[0011] By adopting the above technical solution, when the grain is discharged from the bottom of the conical channel, the grain falls on the conical block, and the side wall of the conical block plays a guiding role, so that the grain can slide smoothly into the space between the adjacent partition plates.
[0012] Optionally, the horizontal grid box includes several guide plates and several diversion plates arranged at an angle, the guide plates and diversion plates being arranged crosswise, and the inclination directions of the guide plates and diversion plates being opposite. A collection box and a storage box are provided below the horizontal grid box. The collection box is used to receive grain on the guide plates, and the storage box is used to receive grain on the diversion plates.
[0013] By adopting the above technical solution, when the grain is poured into the horizontal compartment, it slides on the guide plate and the diversion plate. The cross arrangement of the guide plate and the diversion plate causes some grain to slide down the guide plate into the collection box, while the other part slides down the diversion plate into the storage box, thus initially dividing the grain evenly into two portions. Subsequently, the grain in the collection box and the storage box is poured into the conical channel simultaneously, allowing it to reach the dividing plate along the conical channel and obtain multiple equal portions of grain at once.
[0014] Optionally, the collection box and storage box are arranged symmetrically about the central axis of the conical channel, and the sides of the collection box and storage box that are close to each other are open structures. A stop block is provided inside the working cylinder, and the stop block is located between the collection box and the storage box. The stop block is used to block the openings of the collection box and the storage box. A rotating component is provided on the working cylinder, and the rotating component is used to drive the openings of the collection box and the storage box toward the conical channel.
[0015] By adopting the above technical solution, in the initial state, the collection box and the baffle cooperate to form a box structure with only a top opening. The storage box is similar. When both the collection box and the storage box contain an equal amount of grain, the rotating component is activated to drive the collection box and the storage box to rotate simultaneously, causing the collection box and the storage box to separate from the baffle. This allows the openings of the collection box and the storage box to face the conical channel simultaneously, enabling the grain in the collection box and the storage box to be poured into the conical channel for mixing at the same time, thus improving the uniformity of the grain discharged from the bottom of the conical channel.
[0016] Optionally, the rotating assembly includes two gears and two racks. The gears are fixed to both the collection box and the storage box. The gears are rotatably connected to the working cylinder. The racks are vertically arranged, and each rack corresponds to one gear. The two gears are located between the two racks, and the racks mesh with the gears.
[0017] By adopting the above technical solution, two racks are moved simultaneously, driving two gears to rotate at the same time, thereby making the collection box and storage box rotate synchronously, so as to realize the simultaneous dumping of grain in the collection box and storage box.
[0018] Optionally, an electric push rod is provided on the outer wall of the working cylinder, and a drive rod is connected to the output end of the electric push rod. The drive rod is slidably connected to the outer wall of the working cylinder, and both racks are connected to the drive rod. The movement of the drive rod is used to drive the two racks to move up and down simultaneously.
[0019] By adopting the above technical solution, activating the electric push rod and driving the drive rod to move can drive the two racks to move simultaneously, increasing the consistency of the rotation of the two gears, thereby improving the accuracy of simultaneously pouring grain from the collection box and storage box.
[0020] Optionally, a guide groove is formed on the outer wall of the working cylinder in the vertical direction, and a guide block is fixed on the drive rod. The guide block is inserted into the guide groove and can move in the guide groove.
[0021] By adopting the above technical solution, when the drive rod moves, the guide block moves in the guide groove, and the inner wall of the guide groove abuts against the side wall of the guide block, which restricts and guides the guide block, thereby making it less likely for the drive rod to deflect during movement and increasing the stability of the drive rod movement.
[0022] In summary, this application includes at least one of the following beneficial effects:
[0023] 1. In use, pour the grain into the horizontal compartment. The grain is divided into two equal portions and discharged from the bottom of the compartment, achieving initial separation of the grain. Then, the two equal portions of grain fall simultaneously into the conical channel, where the grain mixes again. At this point, the grain in the conical channel is more uniform, allowing it to be discharged evenly from the bottom of the conical channel. When the grain falls to the dividing plate, it is evenly discharged from the working cylinder between adjacent dividing plates, thus obtaining multiple uniform portions of grain at once. The operation is convenient.
[0024] 2. When the grain is discharged from the bottom of the conical channel, it falls onto the conical block. The side wall of the conical block acts as a guide, allowing the grain to slide smoothly between the adjacent partition plates. Attached Figure Description

Detailed Implementation
[0029] The following is combined with Figure 1-3 This application is described in further detail.
[0030] This application discloses a multi-channel grain sampler. (Refer to...) Figure 1 and Figure 2 The multi-channel grain sampler includes a support 10 and a working cylinder 20 fixed on the support 10. The working cylinder 20 is a square sleeve that runs vertically through the cylinder. A horizontal grid box 30 is fixed at the top of the working cylinder 20. The horizontal grid box 30 includes several guide plates 31 and several diversion plates 32. The guide plates 31 are arranged at intervals, and the diversion plates 32 are inserted between the guide plates 31, that is, there is a diversion plate 32 between every two guide plates 31. One end of the guide plate 31 and the diversion plate 32 are on the same horizontal plane, while the other end is inclined downwards, but the inclination directions of the guide plate 31 and the diversion plate 32 are opposite. A collection box 40 and a storage box 50 are provided below the horizontal grid box 30. The collection box 40 and the storage box 50 are mounted on the working cylinder 20 through a rotating assembly 70. The collection box 40 is used to receive grain on the guide plate 31, and the storage box 50 is used to receive grain on the diversion plate 32.
[0031] Reference Figure 1 and Figure 2 Below the horizontal grid box 30, there is a conical channel 80 for receiving the grain in the horizontal grid box 30. The conical channel 80 is fixed on the inner wall of the working cylinder 20. The inner diameter of the conical channel 80 gradually decreases from top to bottom. The horizontal grid box 30 and the conical channel 80 are coaxial. The rotating component 70 can drive the collecting box 40 and the storage box 50 to rotate, and pour the stored grain into the conical channel 80 from the top opening.
[0032] Reference Figure 2 and Figure 3Below the conical channel 80, there are several partition plates 110. The partition plates 110 are arranged radially with the central axis of the conical channel 80 as the center. The distance between adjacent partition plates 110 is equal. The ends of the partition plates 110 near the central axis of the conical channel 80 are fixed to each other, and the other ends are fixed to the inner wall of the working cylinder 20.
[0033] Reference Figure 1 and Figure 2 A conical block 90 is provided between the partition plate 110 and the conical channel 80. The conical block 90 is fixed on the partition plate 110 and is coaxial with the central axis of the conical channel 80. The top of the conical block 90 is a pointed tip. When the grain is discharged from the bottom of the conical channel 80, the grain falls on the conical block 90. The side wall of the conical block 90 plays a guiding role, which makes it easier for the grain in the conical channel 80 to fall between the adjacent partition plates 110.
[0034] In use, grain is poured into the horizontal grid box 30. The grain slides on the guide plate 31 and the diversion plate 32. The cross arrangement of the guide plate 31 and the diversion plate 32 causes some grain to slide down from the guide plate 31 into the collection box 40, while the other part slides down from the diversion plate 32 into the storage box 50, thus initially dividing the grain into two equal portions. Then, the two equal portions of grain fall simultaneously into the conical channel 80, where they mix again. At this point, the grain in the conical channel 80 is more uniform, allowing it to be evenly discharged from the bottom of the conical channel 80. When the grain falls to the partition plate 110, it is evenly discharged from the working cylinder 20 between adjacent partition plates 110, thus obtaining multiple uniform portions of grain at once, making the operation convenient.
[0035] Reference Figure 1 and Figure 2 To facilitate the collection of multiple equal portions of grain, guide channels 120 are connected between adjacent partition plates 110. Several guide channels 120 are located below the partition plates 110, and the inner diameter of the guide channels 120 gradually decreases from top to bottom. When grain passes through the partition plates 110, it passes between adjacent partition plates 110 and enters the guide channels 120. The guide channels 120 serve to guide and separate the grain, preventing multiple uniform portions of grain from mixing during the fall, thus facilitating the collection of each portion of grain.
[0036] Reference Figure 1 and Figure 2 The rotating component 70 includes two gears 71 and two racks 72. Both the collection box 40 and the storage box 50 are fixed with gears 71. The gears 71 are rotatably connected to the working cylinder 20. The racks 72 are vertically arranged. The racks 72 correspond one-to-one with the gears 71, and the two gears 71 are located between the two racks 72. The racks 72 mesh with the gears 71.
[0037] Reference Figure 1 and Figure 2 An electric push rod 21 is bolted to the outer wall of the working cylinder 20. The output end of the electric push rod 21 is connected to a drive rod 130, which is slidably connected to the outer wall of the working cylinder 20. Both racks 72 are connected to the drive rod 130. The movement of the drive rod 130 drives the two racks 72 to move up and down simultaneously. A guide block 131 is fixed to the side wall of the drive rod 130. A guide groove 22 is formed vertically on the outer wall of the working cylinder 20. The guide block 131 is inserted into the guide groove 22 and can move within the guide groove 22.
[0038] When the electric push rod 21 is activated, the drive rod 130 moves. The inner wall of the guide groove 22 abuts against the side wall of the guide block 131, which restricts and guides the guide block 131. This makes it difficult for the drive rod 130 to deflect during movement, causing the two racks 72 to move simultaneously, thereby driving the two gears 71 to rotate simultaneously. This makes the collection box 40 and the storage box 50 rotate synchronously, so that the grain in the collection box 40 and the storage box 50 can be poured into the conical channel 80 at the same time for mixing, improving the uniformity of the grain discharged from the bottom of the conical channel 80.
[0039] Reference Figure 2 and Figure 3 In order to facilitate the emptying of grain from the collection box 40 and the storage box 50, the collection box 40 and the storage box 50 are arranged symmetrically with the central axis of the conical channel 80 as the axis, and the sides of the collection box 40 and the storage box 50 that are close to each other are open. A stop block 60 is fixed inside the working cylinder 20. The stop block 60 is located between the collection box 40 and the storage box 50 and is used to block the openings of the collection box 40 and the storage box 50.
[0040] In the initial state, the collecting box 40 and the stop block 60 cooperate to form a box structure with only a top opening. The storage box 50 is in the same state. When the collecting box 40 and the storage box 50 are both filled with an equal amount of grain, the rotating component 70 is activated to drive the collecting box 40 and the storage box 50 to rotate simultaneously, so that the collecting box 40 and the storage box 50 are separated from the stop block 60. This allows the openings of the collecting box 40 and the storage box 50 to face the conical channel 80 at the same time. At this time, there is no obstruction in the direction of grain movement, so that the grain in the collecting box 40 and the storage box 50 can be completely poured into the conical channel 80 at the same time for mixing.
[0041] The implementation principle of the multi-channel grain sampler in this application embodiment is as follows: During use, grain is poured into the horizontal grid box 30, and the grain is divided into two equal portions that are discharged from the bottom of the horizontal grid box 30, achieving initial separation of the grain. Then, the two equal portions of grain simultaneously fall into the conical channel 80, where the grain mixes again. At this point, the grain in the conical channel 80 is relatively uniform, allowing it to be discharged evenly from the bottom of the conical channel 80. When the grain falls to the separator plate 110, it is evenly discharged from the working cylinder 20 between adjacent separator plates 110, thus obtaining multiple uniform portions of grain at once, making the operation convenient.
[0042] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
